How does the Rainy Season affect cement and concrete?
During the rainy season leads to a lot of issues in the concrete and cementing process.
Cement plays an important part in concrete, frequently used extensively in construction project. The quality of cement is crucial in determining the strength and durability of concrete. However, in the rainy season, cement has the tendency to absorb moisture from the air, which may affect its quality. Moisture can interact with the cement, causing its premature hardness. This may cause a decrease in workability and concrete strength, potentially resulting in structural issues.
Aside from its effect on cement, the rainy season can also impact the characteristics of concrete. Because of its porous material structure, water has the ability to crack cracks on the exterior in concrete and move through capillary pores to reach the built reinforcement. Once the reinforcement comes into contact with water, it corrodes and expands, causing the formation of more cracks in concrete and causing more water into the concrete. Due to corroded reinforcement, the load-bearing capacity of concrete decreases, while the risk of seepage increases. Cracks happen due to the concrete expanding and contracting in response to temperature and moisture fluctuations. During the monsoon season, the adhesion qualities of concrete may be impacted, resulting in a decrease in bond strength. Due to this, the concrete may detach from the reinforcement, causing structural problems.
In this blog, we will explore why AAC blocks are considered a perfect choice for construction during the rainy season.
Superior Moisture Resistance
One significant benefit of using AAC blocks lies in their remarkable resistance to moisture. Unlike conventional clay brick or concrete blocks, AAC blocks consist of autoclaved aerated concrete blocks that incorporate numerous air voids. These air voids offer superior insulation properties and effectively inhibit water absorption. The closed-cell composition of AAC blocks enhances their ability to withstand moisture infiltration, thereby decreasing the likelihood of dampness, mold formation, and structural deterioration, particularly crucial during the rainy season.
Thermal Insulation Properties
AAC blocks have excellent thermal insulation properties, which are particularly beneficial in regions with heavy rainfall. The air voids in AAC blocks act as insulating pockets, reducing heat resistant and maintaining a comfortable indoor temperature. In contrast to other construction materials, AAC blocks are fire resistant up to 1200℃. Autoclaved aerated concrete is also earthquake resistant because of its lightweight. AAC blocks are more reliable than traditional building material. During the rainy season, when the external environment is cooler, AAC blocks help to keep the interiors warm and prevent issues like condensation and moisture buildup on wall and ceiling.
Long-term Structural Integrity
The use of AAC blocks in construction projects has been proven to significantly increase the long-term structural integrity of buildings.
